Answers
The value of k that will make the quadratic equation kx² - 4x + 1 = 0 to have two equal roots is; k = 4
What are the roots of the Quadratic Equation?The general form of representing a quadratic equation is;
ax² + bx + c = 0
Now, we are given the quadratic equation which is;
kx² - 4x + 1 = 0
Now, for a quadratic equation to have 2 equal roots, it means that;
b² = 4ac
Thus, applying that to our given quadratic equation gives us;
(-4)² = 4(k * 1)

The graph shows the relationship between the number
of cups of flour and the number of cups of sugar in
Angela's brownie recipe.
The table shows the same relationship for Jaleel's
brownie recipe.
Jaleel and Angela buy a 12-cup bag of sugar and divide
it evenly to make their recipes.
If they each use ALL of their sugar, how much FLOUR
do they each need?
Answers
Angela's use 6 cups of flour and Jaleel's use 19/3 cups of flour.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The graph shows the relationship between the number of cups of flour and the number of cups of sugar in Angela's brownie recipe.
And, The table shows the same relationship for Jaleel's brownie recipe.
Hence, The equation for Angela's brownie recipe is,
Two points on graph are (4, 2) and (2, 1)
⇒ y - 2 = (2 - 1)/ (4 - 2) (x - 4)
⇒ y - 2 = 1/2 (x - 4)
⇒ y - 2 = 1/2x - 2
⇒ y = 1/2x
And, The equation for Jaleel's brownie recipe is,
Two points on graph are (3/2, 1) and (3, 2)
⇒ y - 1 = (2 - 1)/ (3 - 3/2) (x - 4)
⇒ y - 1 = 2/3 (x - 4)
⇒ y - 1 = 2/3x - 8/3
⇒ y = 2/3x - 8/3 + 1
⇒ y = 2/3x - 5/3
So, For Jaleel and Angela buy a 12-cup bag of sugar.
The equation for Angela's brownie recipe is,
⇒ y = 1/2x
⇒ y = 1/2 × 12
⇒ y = 6
The equation for Jaleel's brownie recipe is,
⇒ y = 2/3x - 5/3
⇒ y = 2/3 × 12 - 5/3
⇒ y = 19/3
Thus, Angela's use 6 cups of flour and Jaleel's use 19/3 cups of flour.

Where k is a constant and represents the cost of each gallon.
We can see the point (7, 21), replacing these values we will get:
21 = k*7
21/7 = k

The probability that at least one of the employees works at the plant in Texas is 0.993.
Given information:A company, Axline computers, manufactures personal computers at two plants.One plant is located in Texas and the other in Hawaii.The Texas plant has 40 employees, and the Hawaii plant has 20 employees.A random sample of 10 employees is being asked to fill out a benefits questionnaire.Find the probability that at least one of the employees works at the plant in Texas. The probability that at least one of the employees works at the plant in Texas is 0.993.What is the probability that at least one of the employees works at the plant in Texas?For this problem, we can use the Complementary Probability method, which means the probability of an event occurring is equal to 1 minus the probability of the event not occurring. Let's use this method below. Number of employees in Texas plant = 40Number of employees in Hawaii plant = 20Total number of employees = 40 + 20 = 60Let A be the event that at least one of the employees works at the Texas plant.Then the event that none of the employees work at the Texas plant is: A' (A complement). To find the probability that at least one employee works at the Texas plant, we'll find the probability that none of the employees work at the Texas plant, which is easier to calculate. Then, we'll subtract that probability from 1. The probability that the first employee does not work at the Texas plant is:60 employees in total, 40 of them are in Texas plant.So the probability that the first employee does not work at the Texas plant is: 20/60 = 1/3. As we have already picked one employee, there are now only 59 employees left, of which 39 are in the Texas plant. Therefore, the probability that the second employee does not work at the Texas plant is: 20/59. Similarly, the probability that the third employee does not work at the Texas plant is: 19/58. Continuing this pattern, we get the probability that none of the employees work at the Texas plant as: 1/3 * 20/59 * 19/58 * 18/57 * 17/56 * 16/55 * 15/54 * 14/53 * 13/52 * 12/51 * 11/50 ≈ 0.007. Hence, the probability that at least one employee works at the Texas plant is: 1 - 0.007 ≈ 0.993. Therefore, the probability that at least one of the employees works at the plant in Texas is 0.993.

Find an equation for the tangent line to the graph of the following equation at the specified point. y + ry! - 52*y. (x,y) = (1,2)
Answers
The equation for the tangent line to the graph of y + ry! - 52*y at (1,2) is y = 3x - 1. The tangent line has a slope of 3 and passes through the point (1,2).
To find the equation of the tangent line, we need to calculate the derivative of the given equation.
Taking the derivative of y + ry! - 52*y with respect to x, we get dy/dx + ry! - 52(dy/dx). Evaluating this at the point (1,2), we find dy/dx = 3. Now, we can use the point-slope form of a linear equation, y - y1 = m(x - x1), where m represents the slope.
Substituting the values of the point (1,2) and the slope m = 3, we get y = 3x - 1 as the equation for the tangent line.

The formulae for the coordinates of the midpoint are:

Answers
Step-by-step explanation:
To determine if a system of two equations with two unknowns has infinite solutions using matrices, you can perform Gaussian elimination or row reduction on the augmented matrix of the system. If the reduced form of the matrix is the identity matrix, then the system has a unique solution. If the reduced form is a row of zeros except for the last column, then the system has no solution. If the reduced form has a row with all zeros except for the last column being non-zero, then the system has an infinite number of solutions.
In other words, the system has infinite solutions if the row reduced form of the augmented matrix has a row of the form [0 0 c], where c is a non-zero scalar. This means that there is a non-trivial solution that satisfies the equation, indicating that there are infinitely many solutions.

Trinity has 20 quarters and nickels worth a total of $2.00. How many of each coin does she Include introductory statements as well as a concluding statement.
Answers
Answer:
We know that Trinity has a total of 20 quarters and nickels, so:
x + y = 20
We also know that the value of x quarters is 25x cents, and the value of y nickels is 5y cents. The total value of the coins is $2.00, which is 200 cents:
25x + 5y = 200
We now have two equations with two variables. We can solve for one variable in terms of the other in one of the equations and substitute that expression into the other equation.
Let's solve for y in terms of x in the first equation:
y = 20 - x
Substitute this expression for y into the second equation:
25x + 5(20 - x) = 200
Simplify and solve for x:
25x + 100 - 5x = 200
20x + 100 = 200
20x = 100
x = 5
Now that we know x = 5, we can use the first equation to find y:
x + y = 20
5 + y = 20
y = 15
Therefore, Trinity has 5 quarters and 15 nickels.
